Generic Data Type Mnemonics
(changed)
Data types used for intrinsics are represented by generic mnemonics,
emphasizing that intrinsics can be called from all the programming
languages. For example, if an intrinsic is listed as requiring an I32V
parameter, you must pass, by value, a signed 32-bit integer.
The data types and their mnemonics are different in MPE V/E and MPE XL.
The list of mnemonics and their meanings are listed in Table 3-1 and
Table 3-2, following.
